The Effect of Anode Porosity on the Performance of Planar Electrode Supported Solid Oxide Fuel Cell

Based on CFD commercial software and the developed program which involved multi-component flow and diffusion, mass/heat transfer, electrochemical reaction and current field calculation, the performance of planar-electrode-support solid oxide fuel cell with different porosity anodes was investigated. The distributions of species concentration, temperature, electric potential, current and current density were obtained. The results show that this SOFC cell has good performance on species diffusion, current transfer and power output when anode porosity varies between 0.3 and 0.4. This work may be of significance to further research on the anode material.
